argenx to Present New Data from Generalized Myasthenia Gravis Program at 2022 American Academy of Neurology Annual Meeting
April 01, 2022 at 01:00 AM EDT
Presentations demonstrate leadership in FcRn, including an oral presentation of data from the ADAPT+ open label extension study evaluating long-term safety, tolerability and efficacy of VYVGART® (efgartigimod alfa-fcab) in adult patients with generalized myasthenia gravis
argenx SE (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced that interim data will be presented from ADAPT+ at the American Academy of Neurology (AAN) Annual Meeting in Seattle, WA, April 2-7. ADAPT+ is the global Phase 3 open-label extension study evaluating long-term efficacy, safety and tolerability of VYVGART® (efgartigimod alfa-fcab) in adult patients with generalized myasthenia gravis (gMG).
Additional presentations at AAN will include a review of baseline characteristics from the Company’s pre-approval access program for VYVGART, as well as data on the treatment burden of gMG from a cross-sectional study of 152 U.S. adults with a self-reported gMG diagnosis.
“We are thrilled that our ADAPT+ study has been selected for an oral presentation at this important neurology forum, and hope these exciting data will advance healthcare providers’ understanding of long-term therapeutic outcomes with VYVGART as they continue to manage their gMG patients,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx. “We remain as committed as ever to the gMG community, and look toward to offering deeper insight into the patient experience so we may best address their unmet needs and seek to alleviate the burden of this complex, debilitating disease.”

IMPORTANT SAFETY INFORMATION FOR VYVGART® (efgartigimod alfa-fcab) intravenous (IV) formulation (U.S. PRESCRIBING INFORMATION)
What is VYVGART® (efgartigimod alfa-fcab)?
VYVGART is a prescription medicine used to treat a condition called generalized myasthenia gravis, which causes muscles to tire and weaken easily throughout the body, in adults who are positive for antibodies directed toward a protein called acetylcholine receptor (anti-AChR antibody positive).
What is the most important information I should know about VYVGART?
VYVGART may cause serious side effects, including:
Before taking VYVGART, tell your health care provider about all of your medical conditions, including if you:
Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
What are the common side effects of VYVGART?
The most common side effects of VYVGART are respiratory tract infection, headache, and urinary tract infection.
These are not all the possible side effects of VYVGART. Call your doctor for medical advice about side effects. You may report side effects to the US Food and Drug Administration at 1-800-FDA-1088.
Please see the full Prescribing Information for VYVGART and talk to your doctor.
Efgartigimod is an antibody fragment designed to reduce pathogenic immunoglobulin G (IgG) antibodies by binding to the neonatal Fc receptor and blocking the IgG recycling process. Efgartigimod is being investigated in several autoimmune diseases known to be mediated by disease-causing IgG antibodies, including neuromuscular disorders, blood disorders, and skin blistering diseases. Efgartigimod is currently approved in the United States as VYVGART® (efgartigimod alfa-fcab) for the treatment of adults with generalized myasthenia gravis (gMG) who are anti-acetylcholine receptor (AChR) antibody positive and in Japan for the treatment of adults with gMG who do not have sufficient response to steroids or non-steroidal immunosuppressive therapies (ISTs).
About Generalized Myasthenia Gravis
Generalized myasthenia gravis (gMG) is a rare and chronic autoimmune disease where immunoglobulin G (IgG) autoantibodies disrupt communication between nerves and muscles, causing debilitating and potentially life-threatening muscle weakness. Approximately 85% of people with MG progress to gMG within 24 months1, where muscles throughout the body may be affected. Patients with confirmed AChR antibodies account for approximately 85% of the total gMG population1.
